Abstract
The invention provides a flattened heat pipe whose vapor flowing passage is not clogged and which has an excellent capillary force. The flattened heat pipe has a closed container formed by flattening a tubular container, a plurality of wick structures arrayed within the container in a longitudinal direction so as to form an acute-angled portion where a capillary force is large at least partially within the container, a hollow portion formed of an outer peripheral surface of the wick structure and an inner wall surface of the container and a working fluid sealed into the container.
